The instructions that follow will walk you step-by-step through how to program
a Radio Shack Pro-97 scanner to scan Gwinnett County's radio system.
Following the instructions is some information on how to use the scanner, in particular the features that are useful when listening to
Gwinnett.

Entering the Frequencies

The first thing we must do to setup the scanner to listen to Gwinnett County is to enter the radio frequencies used by Gwinnett's system. This will tell the scanner where to tune to hear radio traffic.

Turn the scanner off and then back on.

The first thing we'll do is clear all of the frequencies in the bank you'll use to listen to Gwinnett County.

Press the black F button, then press 0, then press the F button again, then press CL, and then press the 1 button.

Enter 000 and then press PGM to enter programming mode starting at channel 0. On the display the P on the left of the first line of the display says you're in programming mode, and the 000 indicates your looking at channel 0.

Press the orange T button to enter trunking mode.

Press the MODE button until Motorola is displayed on line 2 of the display.

Press the PGM button again to begin entering frequencies. You'll enter 24 frequencies total. If you make a mistake while entering a frequency you can press the CL button to delete the last number entered. If you accidently press the PGM button twice while entering frequencies you can press the down arrow to back-up to the previous location.

Enter the first frequency, 854.78750, then press ENT and then press PGM to go to the next channel.

To double-check that you entered all of the frequencies correctly enter 0 and then the PGM button to go back to the first frequency entered.

Press PGM to go through all 24 frequencies, if you see a mistake enter the correct frequency and then press ENT to save it, continue pressing PGM until you have verified all 24 frequencies.

Next press 0 and then PGM to go back to the first frequency again.

Press the MODE button until you see MO following the channel number on the first line of the display (P000 for example). After MO is displayed press PGM to go to the next frequency.

Repeat step #13 for each of the 24 frequencies.

Entering Labels for the Frequencies

If you're anxious to start scanning you can skip this section and come back to it later (or never). This section instructs you how to enter the text
that displays on line 2 of the display when the scanner stops on a transmission.

Press PGM, enter 000 and then press PGM again to go back to the first trunking frequency in programming mode.

Press the TEXT button, this should cause the cursor to blink in the first column of the second row of the display.

Enter 41 to display G.

Enter 91 to display W.

Enter 43 to display I.

Enter 62 to display N.

Enter 62 to display N.

Enter 32 to display E.

Enter 81 to display T.

Enter 81 to display T.

Press the period to display a space.

Enter 23 to display C.

Enter 63 to display O.

Enter 82 to display U.

Enter 62 to display N.

Enter 81 to display T.

Enter 93 to display Y.

Press the period to display a space.

Press ENT and you should now see "GWINNETT COUNTY" on the third line of the LCD. If you make a mistake you can use the down arrows to back up and make corrections.

Press PGM to go to the next channel.

Repeat steps #2 through #20 for all 24 frequencies.

Programming the Scan Lists with Text-Tags

Now it's time to program the "scan lists" to tell the scanner what talkgroups (Fire Dispatch, Westside Police Dispatch, etc).

For each trunk system that is being scanned the scanner gives you 5 "scan lists" that can each contain up to 30 talkgroups. These "scan lists" allow you to group talkgroups (like Fire Dispatch, Fire TAC 2, etc) into "scan lists" that will allow you to tell the scanner what you want to hear easily.

The instructions below will setup your scanner with the following scan lists:

If 0-0 is not displayed on the first line keep pressiing the T button until it does.
If Motorola is not displayed on the third line keep pressing the MODE button until it does.
If TGID#00 is not displayed on the second line keep pressing the up/down arrows until it does.

When listening you scan in what Radio Shack calls Open mode or Closed mode.

In Open mode the scanner will stop on every transmission whether the talkgroup/channel is programmed (above) or not. In Closed mode
you will only hear transmissions on talkgroups/channels which you have programmed and are scanning. You will most likely want to put your
scanner into Closed mode and leave it there.

To see what mode your scanner is in press MAN, enter 000, and then press MAN again. On line two of the display to the far right you
will see "lo-" or "lo+". If you see "lo-" you are scanning in Closed mode, if you see "lo+" you are scanning in Open mode. To change
the mode press F and then press the period key.

Scanning

Press the SCAN button to start listening.

When you start scanning for the first time after programming the scanner the scanner will scan all 5 scan lists that were programmed:

Scan List 0

Gwinnett Police

Scan List 1

Gwinnett Fire and EMS

Scan List 2

Gwinnett Fire and EMS (Hospital Rescue only)

Scan List 3

Lawrenceville Police

Scan List 4

Other city police departments

You can turn scan lists on and off to listen to only what you are interested in. If you're in the city of Lawrenceville you may want to
listen to only scan list 3, if you're not in a city you may want to listen to only scan list 1, or, if there's a big apartment fire you might
want to listen to only scan list 1 or to both scan lists 2 and 2.

To turn scan lists on and off press PGM and then the orange T button. On line 1 of the display you will see "ID Bank 0-x" where x is
one of the scan lists above. If the display says "ID Bank 0-3" you're currently looking at the scan list 3 (Lawrenceville Police).
On the far right of line 1 on the display you'll see ON or OFF, this indicates whether the scan list is on or off.

Press the T button to change which scan list you are currently looking at. To change whether the scan list is on or off press the F
button and then 1, you'll see ON change to OFF or OFF change to ON.

Hold Mode

While the scanner is stopped on a transmission you can tell the scanner to hold on that channel by pressing and holding the orange T button
until the display says "ID hold ON". In this mode the scanner will only let you hear transmissions on the talkgroup/channel the scanner
is holding on. To resume scanning press the T button a second time.

Priority Mode

The scanner has what is called a priority mode, when on the scanner will stop every couple of settings and check for activity on a
frequency set as a priority frequency. You will want this turned off. When scanning you'll see either "pri--" or "PRIon" at the right
end of the 1st line on the display. If you see "PRIon" press the PRI button to turn priority mode off.

If, later on, you notice there is an interruption in the audio every couple of seconds check to make sure you haven't accidently turned on Priority Mode.

Locking out Talkgroups

The scanner allows you to lock out individual talkgroups while you are scanning. This useful if you do not want to hear radio traffic
on that channel. While you're listening to a transmission press the L/OUT button to lockout that channel, you can unlock it again later by
following the steps below.

You can also lock out talkgroups without hearing radio traffic on them first. You might want to do this if you are in Duluth and only want to listen to Duluth Police and not any of the other city police departments that are in the same scan list. To do this PGM, enter 000, press PGM again, and then press the orange T button.
On line one of the display, to the right of "ID Bank 0-" is the scan list you are currently looking at. Press the T button until the scan
list containing channels you want to lock out is displayed.

On the right-side of line 2 on the display you will see "lo" or "LO". "lo" indicates the talkgroup/channel is not locked out, "LO" indicates
that it *is* locked out. To change the lockout state of a channel press the L/OUT button.

Press the up arrow button to look at all of the talkgroups/channels in the current scan list. After you've checked all of the entries in the
list you can press T to go to the next scan list or press SCAN to start scanning again.

Unlocking Talkgroups

If you have stopped hearing any radio traffic on channels that are normally quite busy you might have accidently locked the channel out.

To see what channels you have locked out (and to unlock them) press PGM, enter 000, press PGM again, and then press the orange T button.
On line one of the display, to the right of "ID Bank 0-" is the scan list you are currently looking at. Press the T button until the scan
list you want to check is displayed.

On the right-side of line 2 on the display you will see "lo" or "LO". "lo" indicates the talkgroup/channel is not locked out, "LO" indicates
that it *is* locked out. To change the lockout state of a channel press the L/OUT button.

Press the up arrow button to look at all of the talkgroups/channels in the current scan list. After you've checked all of the entries in the
list you can press T to check the next scan list or press SCAN to start scanning again.

Key Lock

You can lock the keys on the scanner so that they don't do anything by pressing F and then the light button. To unlock the keys press
F and then the light button again.
